Patented J' an. 23, 1906.

Application iled February 21, 1905. Serial No. 246,701.

To [1J/Z whom it may coneermj Be it known that we, WINFIELD A. HAL- LER, of New Orleans, in the parish of Orleans and State of Louisiana, and JAMES W. BIL- LINGsLEY, of Tivoli, in the county of Dutchess and State of New York, citizens ofthe United States, have invented new and useful Imrovements Vin Manholes for Conduits and the Like', of-which the following is a speciication, Io taken in connectionwith the accompanying drawings, which form a part of the same.

This invention relates to manholes for electric conduits or similar purposes, and relates especially to manholes formed of concrete blocks and provided with internally-projecting shelves Jfor supporting cables, pipes, or the like.

In the `accompanying drawings, illustrating an embodiment of this invention, and in zo which the same reference-numerals'refer to similar parts in both figures, Figure 1 is a partial horizontal section, and Fig. 2 is a vertical section.

In the form of device illustrated in the z5 drawings the bottom 17 of the manhole ma be formed of concrete or other material, pre er'ably of a waterproof character, and a suit-- able drain 15 may be provided to remove any water or moisture. The walls of the manhole may be formed of blocks of suitable contour to correspond with the particular shaped manhole desired, the shape of the manhole being .of course varied to suit the number ofcables which enter it in electrical work. As 3 5 indicated, the manhole may have a large inlet-section at either end and a smaller inletsection at each side of the same, these inletsections being formed of suitable spacingblocks 4 13 14 and the inlet-blocks 7, (see 4o` Figs. 1 and 2,) which are formed with the inlets 8, the smaller lateral inlet-sections being built up in a similar way from the inlet-blocks 9, having one or more inlets 6 therein. The manhole-walls are' preferably formed with shelf-blocks provide with one or more internallyrojecting supporting-shelves substantially inline with the corres onding inlets to support and protect the cab es thu's entering the manhole. These shelf-blocks 11 are in- 5o dicated as formed with a plurality of integral shelves 22, each of which is provided on its upper surface with a series of pockets or supporting-grooves 16 of suitable contour to accommodate the cables and which may, if desired, be formed sufficiently deep to substantially inclose them, and thus in case ofthe accidental burning out of one or more of the cables to protect the other cables in the manhole from damage. It is not necessary that all the blocks forming the manhole-walls between the inlet sections be formed with shelves, and, as indicated in Fig. 2, the lower tier of blocks 12 and the u er tier 5 may be formed without shelves. The shelves are arranged to provide a substantially continuous supporting-shelf coperating wlththe various inlets and extending around the manhole-walls to closely engage and pro erly support a cable throughout substantia ly its entire length within the manhole.

As indicated in Fig. 1, the' various shelfblocks 11, 21, and 20 may be curved in va- Irious ways and the shelves correspondingly formed, so as to properly fit together, suitable spacing-blocks 19 being used where necessary to form a-complete manhole-wall and properly support the to 3, which may be of reinforced concrete an on which rests the collar 2 and the removable cover 1 of ordinary construction, which is substantially on the street-level, as indicated. Each of the blocks forming this manhole-wall is preferably provided with one or more alining grooves 18, running around the same, and these blocks may be alined verticali and horizontally, so as toforrn alining holes om these coperating alining grooves, ,and in this way the whole structure may be 'readily tied to ether by the use of ransome-rods and a suitabe cement or luting which may be poured into or otherwise applied to iill these alining holes.

As indicated, the inlet-section at the end of the manhole is rovided with horizontal rows of siX inlets eac each row of inlets being on substantially the same level as one of the supporting-shelves and each of these shelves being adapted to ing from the corresponding inlets.. -As indicated, he twoupper shelves are interru ted adjacent the lateral inlets 6, so that, de-

sired, cables entering these inlets may be disposed on the corresponding shelves, the other carry. three of the cables issuvzo shelves being indicated as continuous past these lateral inlet-sections. In this way the cable entering each inlet may be provided with a corresponding substantially continuous supporting-shelf extending around the manhole-Wall to the inlet, through which the other end of the cable enters. The nurnber and disposition ofthe supportin -shelves and the arrangement of the shelf-b ocks are of course varied to correspond With the number and disposition of the inlets to the particular manhole.

It is ofcourse understood that those familiar with this art may make many modifications in the form, size, proportion, contour, and numbers of parts of this device, parts of the same may be used without employing the whole, and parts may be used in connection with other devices without departing from the spirit of this invention or losing'the advantages of the same. We do not, there- Jfore, desire to be limited to the details of the disclosure which has been made in this case; but

What we claim as new, and What we desire to secure by Letters Patent, is set forth in the appended claims:

1. In manholes, blocks alined vertically and formed with cooperating alining grooves to form manhole-walls said blocks comprising inlet-blocks and shelf-blocks formed with integral inwardly-projecting shelves provided Withpockets, said shelves cooperating with Said inlets to form substantial y continuous l supporting-shelves around the walls of the manhole between the inlets thereof and on the same level as the corresponding inlets.

2. In manholes, blocks comprising inletblocks and shelf-blocks united to form manhole-Walls, said shelf-blocks being formed with integral inwardly-proj ecting shelves provided With pockets, said shelves coperating with said inlets to form substantially continuous supporting protecting-pockets around the walls of the manhole between said inlets.

3. In manholes, blocks comprising inletblocks and shelf-blocks to form a manhole, said shelf-blocks being provided with a plurality of internally-projecting shelves forming continuous pockets around the walls of said manhole between inlets and on substantially the same level as the corresponding inlets, each of said shelves being provided with a plurality of said pockets.

4. In manholes, walls provided with inlets at different levels and withinWardly-projecting shelves on substantially the same levels as said inlets, the shelves on each level being provided with as many protecting-pockets as there are cables passing through the inlets on said level to provide a substantially continuous protecting-pocket for each cable between inlets.
